Coastal Prop Technology provides each customer with before and finished reports, before means when we first get the propellers and finished is when we have done what your propellers needed whether it was repair or pitch change. We provide you with a packet with the reports including a reinstallation sheet and an ISO standards sheet with the tolerances for the propeller per class. Coastal Prop keeps very good records, we keep a paper file on your vessel and if the vessel is sold it can be transferred to the new owner. All of our props are stamped with a serial number so we can track the prop. Reports are available in paper or pdf file. You can have your paperwork emailed to you or get the packet or both. If you choose to have your propellers dynamically balanced you also get a printed report for that service, showing the amount of grams of weight your propeller was out and the final readout.
